In a large mixing bowl, whisk together the mayonnaise, minced chipotle peppers, lime juice, garlic powder, salt, and black pepper until the dressing is smooth and homogenous.
Add the diced chicken, mango, red bell pepper, red onion, and cilantro to the bowl.
Using a large spoon or spatula, fold the ingredients into the dressing until all components are evenly coated.
Taste and adjust seasoning with additional salt or lime juice if necessary.
Cover and refrigerate the mixture for at least 10 minutes to allow the flavors to meld.
Spoon approximately 1/3 cup of the chicken salad mixture into the center of each lettuce leaf.
Arrange the wraps on a platter and serve immediately, garnished with additional cilantro if desired.
