Unless the rules have changed drastically;
A Renewal, within 12 months of expiration, will need just a renewal flight test, a GFT by day & night on PA-34 in your case.
Your best bet would be to go to any Indian flight school who has a PA-34 & a DGCA authorized/designated examiner to conduct a CPL renewal test on a PA-34.
That will be probably the cheapest way & the one with least hassle....
If you try the 152 route, you will need to pass an exam, then endorsement, almost 6-7 hours, which will be almost the same cost as 2 hours on PA-34.
If you go past 12 months, you will need to pass Air Regs paper also.
After 36 months, ALL PAPERS & ALL CHECK RIDES.
And time FLIES FAST..... I can say that from experience..... Time FLIES FAST..
