rice cooker is the first step. letting the rice sit in the fridge for 12 hours is the second step. making sure those rice grains are dry and spread out on a baking sheet before frying really helps too. and the most important tip that i can give you from experience is just to watch the oil level when frying. Nothing ruins fried rice more than having the rice be too OILY.

Alexthecookingguy on youtube has a great slew of fried rice videos that really helped me.

dark soy sauce and light soy sauce really helps too.
