In a bowl get your dry ingredients and mix together the onion powder, garlic powder, chili powder, salt and pepper. Sprinkle the seasoning mix on both sides of each hamburger patty. In a small bowl mix the mayonnaise and picante sauce in a small bowl until well blended. Set aside. Cook your burgers, my favorite way is on the grill but you could cook them on a skillet over medium heat for about 5 minutes. Then cook them the rest of the way to the way you like your burgers. Once your burgers are cooked place one slice of cheese on each burger and let the cheese melt. Apply a think layer of picante mayonnaise to both sides of bun. Add your lettuce, tomato and onion (as desired) then place your patty on the bottom bun and toppings, top your burger with jalapeno slices and then put the top of the bun on top.
