Cook rice on the stovetop according to the directions on the package, and set aside (note: the rice will take 40-45 minutes to cook, so I recommend cooking it in advance and storing in an airtight container).
Preheat oven to 375 degrees. Place salmon in lined baking dish, rub with olive oil, and season with cumin, paprika, garlic powder, and chili powder mixture. Bake for 35 - 45 minutes or until cooked medium.
While salmon is cooking, lightly toss avocado, red onion, cilantro, mango, and lime juice. Let sit for 10-15 minutes.
Once salmon is done cooking, flake it with a fork assemble tacos on warm corn tortillas as desired.
