"You need to work more on your vocabulary for the next exam."
Vous devez travailler plus ___ votre vocabulaire pour le prochain examen.
What preposition (if any) do we need? The direct translation from English would be sur, but a dictionary has the example travailler son piano, so maybe we don't need anything?
I think that in this sentence indeed, you don't need any preposition.
Actually, it depends what is the "something". If its a discipline (school subject, sport, art...) I would not add anything.
However, you should use "travailler sur quelque chose" if that "quelque chose" refers to a specific task ("travailler sur un projet" par exemple).
Dont hesitate if anyone wants to bring any correction or precision :)
