Cut chicken breasts into bite-sized pieces.
In a bowl, toss chicken with olive oil, chili powder, cumin, smoked paprika, garlic powder, onion powder, cayenne pepper, salt, and black pepper until evenly coated.
Heat a large skillet over medium-high heat and cook the seasoned chicken for 5-7 minutes until browned.
Add chopped chipotle peppers, adobo sauce, and chicken broth. Bring to a simmer, then reduce heat to low, cover, and cook for 10-15 minutes until chicken is cooked through and sauce thickens.
Warm corn tortillas according to package directions.
Fill warm tortillas with the chipotle chicken mixture.
Add desired toppings and serve immediately.
