In a large skillet, heat the olive oil over medium heat. Add the shredded chicken and season with chili powder, cumin, garlic powder, onion powder, smoked paprika, salt, and pepper. Stir well to combine and cook for about 5-7 minutes until heated through and slightly crispy.
While the chicken is cooking, warm the tortillas in a separate skillet or microwave until pliable.
Once the chicken is crispy, remove it from the heat. To assemble the tacos, place a generous amount of the chicken mixture onto each tortilla.
Top the chicken with shredded lettuce, diced tomatoes, shredded cheese, and a dollop of sour cream. Sprinkle with fresh cilantro.
Serve immediately with lime wedges on the side for squeezing over the tacos.
