Season the chicken cutlets thoroughly with smoked paprika, chili powder, garlic granules, salt, and ground black pepper.
Preheat a grill pan, skillet, or outdoor grill over medium heat and add olive oil if using a pan.
Lay the seasoned chicken onto the hot surface and grill on both sides until fully cooked through. Ensure the internal temperature reaches 165°F (75°C).
Transfer the grilled chicken to a plate and allow it to rest for 5 minutes to retain its juices.
Slice the rested chicken into strips suitable for wrapping.
To assemble each wrap, place a tortilla on a clean surface. Begin by layering with a lettuce leaf, then arrange the sliced chicken on top. Sprinkle with shredded cheese and drizzle with ranch dressing.
Fold in the sides of the tortilla, then roll it tightly from the bottom upward, sealing the edges as you go to form a compact wrap.
Place the assembled wrap back on the grill or in a lightly oiled pan. Grill for 1–2 minutes per side until the exterior is lightly crisped and golden.
Remove from heat, slice each wrap in half, and serve immediately.
