In a skillet over medium heat, add olive oil and corn kernels. Sauté for about 5-7 minutes until the corn is slightly charred.
Stir in chili powder, garlic powder, paprika, salt, and pepper. Cook for an additional 2 minutes, then remove from heat.
In a large bowl, combine the shredded chicken, cooked rice, and sautéed corn mixture.
In a small bowl, mix together the mayonnaise and lime juice. Drizzle this dressing over the chicken and corn mixture, and toss to combine.
Serve the mixture in bowls, topped with crumbled cotija cheese, diced avocado, and chopped cilantro. Garnish with lime wedges on the side.
