In a small bowl, stir together the chile powder, salt, cumin, garlic powder, onion powder and black pepper. In a large bowl, mix the cream cheese and green chilis. Add the chicken and toss to coat. Add the seasonings and mix well. Mix in the Monterey jack cheese. Taste and season with additional salt, if needed.

Working with 1 tortilla at a time, spoon about 1/3 cup of the chicken mixture onto the center of the tortilla. Use your fingers to press the chicken mixture into a tight line across the middle of the tortilla. Tightly roll the tortilla around the filling; secure the tortilla in place using one toothpick. (Weave the toothpick through the tortillas where they overlap to close, parallel to the roll). Repeat with the remaining chicken mixture and tortillas.

Preheat the oven to 250°. Heat 1/2-inch of oil in a large cast iron skillet over medium heat until it registers 375°. Fry 4 taquitos, turning occasionally, until golden brown on all sides, 1 to 2 minutes. Transfer to a paper towel lined baking sheet; keep warm in oven. Continue frying until all taquitos are cooked. Serve hot with sour cream, guacamole, Queso and salsa.
