No Google apps and no install zip option in recovery mode
Seems that your recovery got broken, Now you'll have to flash another one the same way you did the first one, via Odin, and i recommend you this version,

CWM_Touch_6.0.4.4_with_Odin

After you flash the recovery, Boot into it, Then select the &quot;GAPPS&quot; version that is compatible with the ROM version you've installed, If you don't have it, Just choose the compatible one from this thread

GAPPS_ALL_VER

Once you flash GAPPS, you're done.
