Preheat the oven to 400 degrees F. Lightly coat a deep, 9x9-inch baking dish or other 2 quart casserole dish with cooking spray. Cook and shred chicken, following these easy steps*.
In a large bowl on medium speed, beat together the cream cheese, Greek yogurt, chili powder, cumin, garlic powder, and salt until smooth and well combined. Reduce speed to low then beat in the enchilada sauce until incorporated. With a rubber spatula or wooden spoon, stir in the beans, tomatoes, corn, 1/2 cup cheddar cheese, and shredded chicken.
Transfer the mixture to the prepared baking dish. Top with remaining 1/2 cup cheddar cheese. Bake for 25-30 minutes, until the dip is hot and the cheese is bubbly. Sprinkle with cilantro, then serve warm with tortilla chips.
