ETA: Not sure about LGBTQ authors, since I often don't know their orientation (as opposed to their characters' orientation.)

But if this is helpful, here's a few books by authors of color I happen to already have on hand: The Eddie book by Marjorie Liu, and from the bookcase photos, the three Haikasoru books, Meji, Manifest, Crystal Rain, City of Fire, My Family and Other Saints, and (already nominated) Shadow Speaker.
