In a large skillet, heat oil over medium heat. Add 1 tortilla and cook for 3-4 minutes, turning once, or until golden and crisp on both sides. Remove the tortilla and set it on a paper towel to drain any excess oil. Repeat with all the tortillas.
In a bowl, mix together tuna, mayo, pickle relish, garlic powder, salt and pepper. Top each tortilla with the jalapeño tuna salad then add desired toppings. Enjoy!
