In a large bowl, add cream cheese, sour cream, and mayonnaise. Mix until smooth and well combined.
Add corn, cheese, green chiles, cilantro, garlic powder, onion powder, paprika, cumin, salt, and pepper. Stir everything together until thoroughly combined, and the dip looks evenly mixed.
Cover the bowl with plastic wrap and refrigerate for at least 1 hour to let the flavors meld and for the dip to fully chill.
Before serving, give the dip a good stir. Transfer to a serving bowl, then sprinkle with a little extra paprika and chopped fresh cilantro for color and flavor.
Serve cold with tortilla chips.
