Well, vassal states can be considered as semi-autonomous entities and may still function without much difference prior to vassalization so long as it did not lose as much of its internal sovereignty and socio-cultural identity. So a capital is still necessary for a vassal state.

Their real roles would lie in the implementation of state-level policies enacted by their master state, this would generally include state-wide laws and military ventures.
