In a large bowl, combine the shredded chicken, crumbled bacon, cherry tomatoes, and diced avocado.
In a small bowl, mix together the mayonnaise, lemon juice, salt, and pepper to create the dressing.
Pour the dressing over the chicken mixture and gently toss until everything is well coated.
Place a lettuce leaf on each tortilla, then spoon the chicken salad mixture evenly onto each.
Wrap the tortillas tightly, folding in the sides as you roll them up.
Cut each wrap in half and serve immediately.
