In a medium saucepan, combine white rice and chicken broth; bring to a boil, then cover and simmer on low for 15 minutes.
Toss cubed chicken with chili powder, garlic powder, and olive oil in a mixing bowl.
Heat a large skillet over medium-high heat and sear the chicken for 8-10 minutes until the internal temperature reaches 165 degrees Fahrenheit; remove chicken and set aside.
In the same skillet, add corn kernels and cook undisturbed for 3-5 minutes until charred; remove from heat.
In a small bowl, whisk together Greek yogurt, mayonnaise, smoked paprika, and half of the lime juice.
Fold the yogurt mixture and cotija cheese into the charred corn.
Fluff the cooked rice with the remaining lime juice and chopped cilantro.
Assemble the bowls by layering the cilantro-lime rice at the base, topped with the seasoned chicken and the street corn mixture.
