In a bowl, mix together the olive oil, garlic powder, onion powder, smoked paprika, cumin, salt, and pepper. Rub this seasoning mixture all over the chicken breasts.
Heat a skillet over medium heat. Add the seasoned chicken breasts and cook for about 6-7 minutes per side, or until the chicken is fully cooked and no longer pink in the center. Remove from heat and let it rest for 5 minutes before slicing it into thin strips.
In a separate pan, lightly warm each flour tortilla for about 20-30 seconds on each side, just until pliable.
Lay a tortilla flat on a clean surface. Start with a layer of brown rice, followed by black beans, corn, diced tomatoes, lettuce, sliced avocado, and a handful of the cooked chicken strips.
Drizzle a generous amount of Chipotle Ranch dressing over the top of the fillings.
Fold in the sides of the tortilla and roll it up tightly from the bottom to encase all the filling. Repeat the process for the remaining tortillas.
Cut the burritos in half diagonally and garnish with fresh cilantro on top. Serve with extra Chipotle Ranch dressing on the side for dipping.
