Being so far out of currency, you no longer qualify for accomplishing the required 6 approaches/6 + 6 month thing. What you're in need of is an Instrument Proficency Check (IPC) check in particular. The requirements for an IPC check are outlined in the front of the Instrument Rating PTS. It differs from what is required for 6 month currency. For instance, you will need to perform unusual attitudes, something not required for the 6 month currency.
Chances are that during the CFII training you will cover all the necessary requirements with your instructor who should be able to endorse you for another 6 months. Don't forget that you'll normally be PIC on your checkride, although that of course can be negotiated with the examiner, but most like to not have that responsibility.
