Heat your deep fat fryer to 175° C/ 350° F.
Remove the chicken from the yogurt. Use some paper towel to remove any excess marinade and pat dry.
WARNING: THROW OUT THE USED YOGURT MARINADE IMMEDIATELY. Do whatever you can to not accidentally use this as your burger sauce.
While your fryer is heating, mix together 1/2 c - 65 gr of flour, 1/2 c - 65 gr cracker meal, 1/2 c - 65 gr of grated Parmesan, 1 t - 5 gr of garlic powder, 1 t - 5 gr cayenne and 1 t - 5 gr of salt in a shallow plate. Line another shallow plate with paper towels to rest your chicken after frying.
Once your deep fat fryer has reached the right temperature, dip your chicken in the cracker/ Parmesan mixture, shake off any excess flour and slowly lower into your deep fat fryer. Be sure to lower your basket into the fat before you do this, so you can easily fish your chicken out once it's ready. Do not lower the chicken in with the basket as they will stick together.
The chicken will take 7-14 minutes to cook, depending on how thick your thighs are. Be sure to wait until your crust is nice and golden brown. Let the chicken rest and drain on your pre-lined plate.
While the chicken is frying, cut open your burger buns and grill them cut side down, fry up the bacon rashers and cook or fry your eggs if using.
