He is working alongside Japanese artistic team Gurihiru on Dark Horse Comics's digest, spinning out of Nickelodeon's acclaimed animated television show, Yang revealed on his blog.
Avatar: The Last Airbender volume 1 - The Promise will follow on from where the original series left off.
The show's creators Michael DiMartino and Bryan Konietzko are working closely with Yang on the project.
"This series of digests rejoins Aang and friends for exciting new adventures, beginning with a faceoff against the Fire Nation that threatens to throw the world into another war, testing all of Aang's powers and ingenuity," said Dark Horse in its solicitation.
Gurihiru provided artwork for some of the stories in Avatar: The Last Airbender - The Lost Adventures.
Yang wrote a short Avatar webcomic last year protesting the predominantly Caucasian casting of M Night Shyamalan's live action movie adaptation of the show.
Avatar: The Last Airbender volume 1 - The Promise will be released on January 25.
