In a bowl, combine the chicken thighs, fish sauce, black pepper, garlic powder, water, and starch until everything is well mixed.
In a separate bowl, prepare the glaze by mixing together the fish sauce, white sugar, water, lime juice or vinegar, along with the minced garlic and chilis.
Heat a pan over medium heat, adding a little oil if necessary.
Pour the chicken mixture into the pan and cook until one side is golden brown.
Carefully flip the pancake and brush the top with the prepared fish sauce glaze.
Continue cooking until the other side is golden brown and the chicken is fully cooked.
