In a large skillet, cook the onion in the vegetable oil over medium heat just until softened - about 5 minutes. Add the garlic, chili powder and cumin and cook, stirring, for another minute or two. Add the rice, black beans, chicken and chicken broth and continue to cook, tossing gently, until everything is heated through.
Roll up mixture in warmed tortillas and garnish with toppings.
