I believe there is an option (in Galactopedia) to limit your viewing to techs that belong to a specific civ. There should be a drop-down list in the upper left-hand corner that allows you to switch between all techs and civ-specific techs, though it will still list techs that other civs may be able to get.
As far as a list of civ-specific techs only, I am aware of none, though it wouldn't be too hard to make. It would just take some time.
