What kinds of aspects should Asian dragons have compared to Western ones?

Serpentine. No wings.
Chinese and Japanese dragons are not affiliated with fire in any way, but with water, and they don't produce water, but rather control it in all of its forms.
In China they are a symbol of luck and generally pleasant things, so in demeanor they shouldn't be aggressive or hostile. Cannot remember whether that was always the case outside of China, but considering the influence of Chinese culture on other East Asian cultures, it's probably safe to assume so.

Dragons are also associated with floods, and possibly due to their serpentine bodies, poison. Dragons are typically shown to own treasures, the more powerful/important ones own entire underwater mansions, but basically all dragons at least one a pearl roughly the size of an adult male's fist.

Dragons possess intelligence as well. At a low end, they're at least as smart as a gorilla, with the more powerful ones being basically superhuman intellects.

Asian Dragons seem to be, fundamentally, associated with very similar set of base symbolism as the western ones: the main difference however being in fundamental attitudes that people have towards those.

All dragons seem to at their heart similar idea: a chimeric being heavily derived from a snake that represents chaos or "natural state of things" (which is generally chaotic), being guardians of treasures or items of desire and representing power or might. All of these symbolic qualities are actually interconnected ideas.
This also explains why they tend to be associated with either fire or water (both being pretty good embodiments of chaotic and powerful elements)

The main difference is that while particularly in Christianized West, the idea of a dragon began FUNDAMENTALLY skew towards being unquestionably evil (presumably as Christian perspective towards nature is rather patronizing, anthropocentric and dominant), in Asia they gained generally much more neutral, or even possitive associations.
In China in particular, Dragons are often depicted as rulers and kings of "natural kingdoms", as conscious, clever beings that don't inherently think vindictive towards people. They are still often protectors of treasures or objects of desire, but unlike in Western cannon they often part with their gifts willingly, upon testing people rather than fighting them. They tend to be described as living in palaces, capable of talking, of taking on human forms, having their own dominances, their own servants and subjects. Asians do not put emphasis on carnal desires, hunger or selfish treasure hogging like we tend to.
They are also associated much more with the positive impacts of natural chaos: namely with water and rain, often being seen patrons of agriculture.

That still does not make them purely positive or kind beings. They still represent chaos and natural forces beyond our immediate control. (cont.)

Serpentine Drakes with deer-like horns, carp like whiskers and instead of breathing fire they use magic to manipulate wind and storms.

Just use a Storm Drake template.

They are usually depicted as fast and impossible to catch while they rule the skies with their power.

Their other abilities and associations are usually tied to :
>Shapeshifting
>Male fertility and fucking anything that moves
>Agriculture and Storms
>Being the king of all beasts...Except for Tigers who are the only beasts that can compete with them on land.

Their treasures usually include:
>Dragon pearls containing their concentrated magic power (This is where dragonball got its inspiration from)
>Plants that grow thanks to their salvia dripping on a piece of land they sleep on for a few decades.
>Usually a shitload of other magic plants because Asian dragons don't hoard gold/silver but food stuffs, magic items and other wondorous shit.

Similarly to pre-christian West, due to their association with power and "natural state of being", they have always been popular in symbolism of ruling families, which is why dragon has actually been chosen as Chinese Imperial symbol, among many others things.

All that said, there are some exceptions from these notions. Most of this actually seems to focus primarily on chinese-rooted culture. In pre-Chinese influenced Japan, the image of a dragon may have been very different: as illustrated by the myth of Yamata-no-Orochi, one of the oldest and most famous myths of Shintoistic Imperial cult.
In this myth, Yamata-no-Orochi is a dragon with eight heads and eight tails who (very similarly to European folklore) seem to have a spacial craving for eating virgin girls and drinking alcohol. He is murdered by the Storm-God Susano-oo, who also finds a sacred sword in one of his tails. Yamata is much more classical image of a dragon, closer to western iconography than to the Chinese one.

Finally, it's worth mentioning that while being described as snake-like, Eastern dragons often have more associations with fish (again, stressing out the association with water, more than fire) - some Japanese folklore tales actually claim that dragons can be born of carps under certain conditions. All that said, it's WRONG to claim that eastern dragons are never associated with fire. They are - some breathe fire, others are surrounded by it, or have their back made out of it.

As for purely physical properties:
Most East-Asian dragons have very long, serpentine or eel-like body covered in scales (and sometimes surrounded by fiery halo), usually with four legs, though sometimes without any, a dog-like head with human beard, sometimes lion mane, and usually deer-like antlers and catfish-like whiskers. The mane and beard can also sometime be fiery. They never have wings, but mostly are described as flying/swimming for air. They frequently shape-shift into people, and cast spells.

Consider me educated, folklore user. This was rather edifying.

Like many divine figures in Chinese mythologies, certain Chinese dragons are actually not very highly regarded by the Chinese themselves - it very much depend on said dragon's social connections (to the higher-ups in the heaven), and his importance.

They're basically extremely intelligent and powerful beasts...but beast nonetheless, and can be exploited and abused.

Notable examples of dragon suffering in Chinese mythologies:

1) Sun Wukong (the Monkey king) blackmailed the Dragon King for fun and profit (to be fair, he shitted all over everyone he came across).

2) Nezha goes playing water at the beach, stir up
great underwater earthquake that nearly destroyed Dragon's realm undersea (because it amuse him). And when the dragon prince tried to protest, he fucking killed the dragon, extracted his dragon-sinew to be made into a sash, and gift it to his dad.

3) A dragon king has a bet with a completely mundane human on rain prediction...well, the heaven decided to side with said human for no reason and FORCED the dragon king to make it rain so that the human can win the bet. He refused, and get killed for his trouble.

Oh, and the Judge of Hell ALSO sided with the human, so not only he is killed, his soul got dragged into the cycle of infinite reincarnation and suffering.

Some Chinese dragons do have wings.
Specifically, Yinglong has wings.

If you're homebrewing, you could have Western dragons be of "water, Earth, air, and fire" aspects and let Eastern dragons follow that Eastern elemental model with Metal, Wood, etc.
