Preheat the oven to 400 degrees F. Heat the vegetable oil in a large skillet over medium-high heat. Add the tortillas and cook, flipping a few times, until golden, about 3 minutes. Remove with tongs and transfer to a paper towel-lined plate to drain. Add the onion to the skillet and cook, stirring, until soft, about 3 minutes. Add the garlic and cayenne and cook 30 seconds. Add the pork and 1/4 teaspoon salt and cook, breaking up the meat, until browned, about 4 minutes. Stir in the tomatoes, chiles and corn. Bring to a simmer and cook until slightly thickened, about 3 minutes. Season with salt. Remove from the heat and stir in the cilantro. Arrange half of the tortillas in the bottom of a 9-to-10-inch pie plate. Top with half of the meat mixture, then half of the cheese. Repeat with the remaining tortillas, meat and cheese. Cover loosely with foil and bake until the cheese melts, about 10 minutes.
