Preheat oven to 425 degrees Fahrenheit (218 degrees Celsius) and line a large baking sheet with parchment paper.
In a medium mixing bowl, combine the shredded chicken, softened cream cheese, salsa, chili powder, cumin, garlic powder, and salt.
Fold the shredded Mexican blend cheese into the chicken mixture until evenly distributed.
Warm the corn tortillas in a microwave for 30 to 45 seconds wrapped in a damp paper towel to prevent cracking during rolling.
Place 2 tablespoons of the chicken filling in a line just off the center of each tortilla.
Roll each tortilla tightly around the filling and place them seam-side down on the prepared baking sheet.
Lightly brush the exterior of each rolled tortilla with vegetable oil using a pastry brush.
Bake for 15 to 20 minutes until the tortillas are golden brown and the ends are crispy.
Remove from oven and allow to rest for 2 minutes to set the filling before serving.
