In most Percy Jackson fanfiction, it often involves some sort of magical or mythical event. Maybe you die heroically in the mortal world and are then chosen by the Fates to be reincarnated as a god. Or it could be through a powerful magic spell that goes awry and instead of something else, turns you into a god.
There are various ways. It could be related to a special prophecy. For example, if there's a prophecy that talks about a new god rising from the ashes of a great battle. You might be a mortal caught in that battle, and due to your actions during it, you get reincarnated as a god. Another way could be through a deal with an existing god. If you manage to strike a bargain with a god who has the power to transform you, you could end up as a god in the Percy Jackson fanfiction world.
Often in Percy Jackson fanfiction, becoming reincarnated as a god might be tied to a unique item or location. There could be a magical spring that, if drunk from, can transform you into a god under the right circumstances. Or it could be an ancient artifact that, when activated by the right person (you), causes you to be reincarnated as a god. It also depends on how the author of the fanfiction wants to set up the rules for this transformation, as there's a lot of creative freedom in fanfiction.
