Clan is not an EQ term. By clan do you mean guild (large group of players that sometimes raid together, and progress together)? If so, check the bulletin boards in the Guild Lobby in the South-East corner of the center area of Plane of Knowledge (PoK), straight South of the Bazaar zone line. If you don't know how to get to PoK, ask in-game or use the map find tools on the map window (M or Backspace forget which is default).
May also look in and possibly post in the SoE Guild Recruitment forum at http://forums.station.sony.com/eq/index.php?forums/guild-recruitment.25/
and look at your specific server's forum (ask in-game in /general if not f2p, or /ooc in the Guild Lobby if you are f2p).
