Preheat oven to 350°F (175°C).
Mix shredded chicken with chili powder, garlic powder, cumin, salt, pepper, and 2–3 tablespoons of enchilada sauce.
Sauté onions & minced garlic a little bit in a skillet or pan and mix into the shredded chicken.
Warm the corn tortillas in microwave, oven or skillet so they roll easily.
Spread a thin layer of enchilada sauce on the bottom of a 9×13 baking dish.
Add chicken mixture and a little cheese into each tortilla, then roll and place seam-side down in the dish.
Pour remaining sauce over the top and sprinkle with the rest of the cheese.
Bake for 20-25 minutes, until cheese is melted and bubbly.
Rest 3-5 minutes, then garnish with fresh cilantro before serving.
