I expect you'll be able to get back into Thailand with a tourist visa. Just expect to be pulled aside and questioned and if you're not then all the better. Also make sure you have the 3 proofs:
1. Proof of funds (20,000₿ or equivalent in another major currency IN CASH ONLY)
2. Proof of leaving Thailand within the 60 days the of the visa (any ticket out of the country will suffice. You can Google onward travel ticket)
3. Proof of lodging (hotel reservation for the first 1-2 weeks. (it's probably better if your provide a hotel reservation rather than a long term lease because that would show you're not a tourist)
