Well, start by brainstorming ideas. Maybe you can jot down some interesting scenarios or character interactions. Look at the existing fanfiction in the same genre for inspiration. Also, make sure you have a good understanding of the original work's universe and rules. If it's a science - fiction based fanfiction, you need to keep the scientific concepts in line with the original, if any.
