Honestly, it's a rather unusual topic for a fanfiction. But if it exists, it could be part of a more comical or angsty story. Comically, it could be something like Jacob ate something really strange in his wolf form and had a bad reaction. Angst - wise, it could be related to some emotional turmoil that manifests physically. But again, you'll have to do a thorough search on the relevant fanfiction platforms to find such stories.

When writing a 'Twilight Jacob vomiting' fanfiction, start with a strong plot idea that incorporates this rather unique event. You could base it on his werewolf nature.

As for the actual vomiting part, describe it vividly but not too graphically. You can use it as a turning point in the story, perhaps leading to a discovery or a change in his relationships.
