Cook the rice according to package instructions and set aside in a warm place.
In a medium bowl, toss the cubed chicken breast with 1 tablespoon of olive oil and the taco seasoning until evenly coated.
Heat the remaining tablespoon of olive oil in a large skillet over medium-high heat and sauté the chicken for 8 to 10 minutes until cooked through and golden brown.
Remove chicken from the pan and in the same skillet, sear the corn kernels for 5 minutes until they begin to char.
In a small mixing bowl, whisk together the mayonnaise, Greek yogurt, lime juice, chili powder, and smoked paprika.
In a large bowl, combine the charred corn with the mayonnaise mixture, crumbled Cotija cheese, and chopped cilantro.
Assemble the bowls by portioning 1/2 cup of rice, 4 ounces of chicken, and a generous scoop of the street corn mixture into four containers.
