In the Occlumency lessons that Snape gives Harry in OotP, it says:
ʹYes, Potter,ʹ [Snape] said, his eyes glinting. That is my job. Now, if you are ready, we will start again.ʹ He raised his wand. ʹOne — two ‐ three ‐ Legilimenslʹ A hundred Dementors were swooping towards Harry across the lake in the grounds… he screwed up his face in concentration… they were coming closer… he could see the dark holes beneath their hoods… yet he could also see Snape standing in front of him, his eyes fixed on Harryʹs face, muttering under his breath… and somehow, Snape was growing clearer, and the Dementors were growing fainter… Harry raised his own wand.
and
ʹSo,ʹ he said. ʹHave you been practising?ʹ ʹYes,ʹ Harry lied, looking carefully at one of the legs of Snapeʹs desk. ʹWell, weʹll soon find out, wonʹt we?ʹ said Snape smoothly. ʹWand out, Potter.ʹ
It seems very clear here that you need a wand both for Legilimency and Occlumency.
Wandless magic, I think, depends on the magical power of the caster. It must be possible to Occlude wandlessly because otherwise Snape could not have kept his mind closed when in the presence of Voldemort, without him noticing.

Interesting question. :)
