Well USB OTG is used in many phones and tablets so there are OTG ethernet adapters like these

or OTG flash drives like these http://www.kingston.com/en/usb/otg
or card readers liek these
as for wifi - most phones/tablets already have wi-fi so such adapter is less likely but I would't say there is no chance
but anyway there are those small adapters like these http://www.ebay.com/itm/251999412567
so putting small wifi adapter into this can still be pretty small
