As Whopity says above. You will need an LST not LPC (raw data ILS in addition to the usual LPC items). If you're licence is issued in Spain, go through the Spanish DGAC and see what paperwork they require (not all EASA states are the same!). A Spanish ATO would make the process much easier I am sure.
If your MEP has expired you will likely need some refresher training at an EASA ATO before doing a proficiency check/renewal.
The big question is will the DGAC accept your Chinese A320 experience or will they require a type course before you do the LST? Were you issued an A320 rating on your EASA licence?
