Depending on where you are and how cold it gets I'd wait till late Feb/early March and then get in there with some big loppers and a pruning saw and prune it back to a good framework. What shape that takes depends on whether you want it more or less rounded and shrub/tree shaped or a flatter, more espaliered form.
Looks to me like you have 4 or 5 good strong stems coming up from the centre and forming a vase shape so I'd leave those and clear everything else down to ground level.
Doing such a heavy prune will provoke plenty of new growth which will need tidying up later in summer to establish a decent shape. Have a read of this info on figs from the RHS. Scroll down for the bit on pruning.
