Sorry to be the bearer of bad news, but Yoda is not a Lannik. Master Even Piell of the Jedi Council is an example of a Lannik. Lannik are more humanoid while Yoda seems to have a reptilian/amphibian link. A recent quote regarding this: "For reasons unknown, George Lucas maintains a strict policy of keeping the history, name, origin, and whereabouts of this species unknown. This policy has resulted even in certain Star Wars publications being canceled."
