In a mixing bowl, combine olive oil, lemon juice, garlic powder, paprika, salt, and black pepper. Add the chicken strips and marinate for at least 15 minutes.

Preheat the grill to medium-high heat.

Grill the marinated chicken strips for about 6-7 minutes on each side, or until fully cooked and no longer pink in the center.

Lay a tortilla flat on a cutting board. Place a handful of lettuce, diced tomato, cucumber slices, grilled chicken, and shredded cheese in the center.

Drizzle ranch dressing over the filling.

Fold in the sides of the tortilla and then roll it up tightly from the bottom to the top.

Repeat with the remaining tortillas and filling.

Cut each wrap in half and serve immediately.
