In a large bowl, combine the shredded chicken, Monterey Jack cheese, green chiles, cilantro, garlic powder, onion powder, cumin, salt, and black pepper. Mix well until all ingredients are evenly incorporated.
Heat a small amount of cooking oil in a skillet over medium heat. Lightly fry each corn tortilla for about 15-20 seconds on each side until they are pliable. Remove and place on a paper towel to drain excess oil.
Preheat your oven to 400°F.
Take a tortilla and spoon about 2 tablespoons of the chicken mixture onto one end. Roll the tortilla tightly around the filling and place seam-side down on a baking sheet. Repeat with the remaining tortillas and filling.
Lightly spray the taquitos with cooking spray or brush with a little oil. Bake in the preheated oven for 15-20 minutes or until golden and crispy.
Serve warm with your favorite dipping sauces, such as salsa or guacamole.
