When I go to tekkit, only 3 mods load. NEI, optifine, and forgemodloader. How can I get the mods back?

are mods' files present in mods directory (USER_DIR\AppData\Roaming\.techniclauncher\tekkit\mods\)? if not, try re-downloading tekkit (changing version in launcher to other and then back, it should download all files again).
