Add chicken tenders and buttermilk in a bowl and let rest (at least 30 minutes, up to 8 hours) in refrigerator.
In a large saute pan over medium high heat, add bacon and cook until crispy. Remove to paper towel covered plate. Reserve all grease in the pan.
In a bowl, combine corn, cilantro, one tablespoon of tajin, lime juice, salt and half of cojita cheese.
In a separate small bowl, combine sour cream, remaining tajin and cumin.
Add flour, baking powder, salt, pepper, garlic and paprika to a bowl and stir to combine.
Add enough oil to the bacon grease to be one inch deep. Once hot (around 350degF), begin frying chicken. Remove each piece of chicken from buttermilk and put right into flour mixture. Fully coat with flour and place right into hot oil. Cook for 4 minutes on each side and remove to a baking rack over a paper towel covered baking sheet. Repeat with remaining chicken tenderloins.
Once all chicken is cooked and slightly cooled, cut each tenderloin into 3-4 pieces (about 1-inch chunks).
Smear tortilla with sour cream mixture. Add 3-4 chunks of chicken to a tortilla. Spoon corn over top then add bacon and sprinkle with remaining cojita cheese.
