Though it wasn't my intent to do a book for indigenous representation alone, I do like to feel like I'm doing a small part to bolster the cause by helping to bring David's Yanomami story to life. Doing a Google search of "Indigenous voices in graphic novels" won't bring up a whole lot in the popular comics sector, aside from X-Men's Mirage, but there are quite a bit more than might be expected on the indie side. For many decades there was no representation, or if there was consisted of tropes and stereotypes. 

Here are just a few from recent years:

Moonshot is an anthology featuring Indigenous writers and artists retelling traditional stories alongside ones of Indigenous futurism

Kagagi: The Raven is an Algonquin superhero story that became an animated TV series in Canada, including a version with 100% Algonquin dialogue

7 Generations follows a Plains Cree family through 7 generations to modern day

Shout Out is an anthology series featuring LGBTQ2S stories, including a Two-Spirit story, called “The Fisher and The Jeweler”

There's also even an Indigenous Comic Con.
