In a bowl, mix together the flour, garlic powder, paprika, thyme, salt, and pepper.
In a separate bowl, beat the eggs.
In a third bowl, add the breadcrumbs.
Dip each piece of fish in the flour mixture, then the beaten egg, and finally the breadcrumbs, pressing lightly to ensure they stick.
Heat a large frying pan over medium-high heat and add enough oil to cover the bottom of the pan.
Once the oil is hot, add the fish nuggets in batches and fry for 2-3 minutes on each side, until golden brown and crispy.
Transfer the cooked fish nuggets to a paper towel-lined plate to drain off any excess oil.
Serve hot with tartar sauce or your favourite dipping sauce.
