Cook the Chicken: Heat olive oil in a skillet over medium-high heat. Add the chicken, chili powder, smoked paprika, cumin, garlic powder, onion powder, salt, and black pepper. Cook for 6-8 minutes, stirring occasionally, until the chicken is golden brown and fully cooked.
Prepare the Street Corn: In a mixing bowl, combine corn, mayonnaise, sour cream, cotija cheese, lime juice, chili powder, and chopped cilantro. Stir well.
Assemble the Bowl: Divide the cooked rice into bowls. Top with the seasoned chicken and the street corn mixture.
Garnish and Serve: Add optional toppings like avocado, jalapeños, hot sauce, or extra cotija cheese. Serve with lime wedges on the side.
