Asian actor or Asian American actor
James Wan, Justin Lin, and Ang Lee are all pretty popular Asian directors in America, of course they aren't American born so I'm guessing that doesn't count for you.
There could be many more absolutely, but these few (and a couple others) have been penetrating into Hollywood.
In terms of Actors it's a bigger issue. It's not so much Asian Americans are being pushed aside, it's more that they aren't even considered. This is a snake eating its own tail problem because very few Asian actors get into films in the first place, so the pool casting directors are looking at is already self-selectively small because there aren't many Asian Americans who have "proven themselves" to be in films. The few Asian actors who have gained some presence are usually in TV and there's still a dumb separation between "TV Actor" and "Film Actor" a lot of the time. That separation has been continually weakening but it hasn't completely evaporated yet. And it's still a lot tougher for a TV Actor to break through into Film than for a Film actor to decide to want to do a TV show.
All that aside you also have writers in general not writing many parts for Asian Americans, or the roles they do write that could be for any race aren't seen as roles that Asians can fit (for various reasons).
Not saying any of that is -right-, just that is how the system is currently working. Which, yes, makes it very hard to be an actor if you're of Asian descent, especially in films. It's not as simple as Executives saying "We don't want any Asians".
Naturally, they could always go with unknown actors, but there's a big aversion to that 90% of the time regardless of race. The other 10% they do specifically try to find unknown actors (or relatively unknown ones at least) because they don't want someone who has been seen before...but it's kind of rare. Notable example of it happening recently is The Force Awakens, of course.
A few up and coming Asian actors to watch for:
Pom Klementieff (Guardians of the Galaxy 2)
Kelly Marie Tran (Star Wars: The Last Jedi)
Riz Ahmed (The Night Of)
Jamie Chung (Once Upon A Time/Gotham/New X-Men show)
Steven Yeun (The Walking Dead)
Benedict Wong (Marco Polo/Doctor Strange)
Those aren't all of them, but there could of course be a lot more.
