Thank you for your query. The first stop for any immigration queries you may have is always the TIMATIC system which lists the relevant visa /immigration requirements for the use of airline check-in employees at check-in. This system is publicly available through the Delta airlines website, here:
Visa & Passport Information
If you enter Filipino nationality going to Thailand, you get the following requirements:
***********************
Passport required.
- Nationals of Philippines can enter with passports and/or
passport replacing documents valid for the period of
intended stay.
Visa required, except for A touristic stay of max. 30 days
Visitors over 12 years of age are required to hold
sufficient funds to cover their stay (at least THB 10,000.-
per person or THB 20,000.- per family).

- For those who do not require a visaFor details, click here
Warning:
- Visitors who are visa exempt but do not hold return/onward
tickets could be refused entry.
*************************
So if you are
definitely visiting Thailand as a tourist, all you should need is your Phillippines passport, a valid return ticket to the Philippines within 30 days and proof of funds (THB 10,000 per person).
Because you worked in Thailand before, and possibly also because of your nationality, you might get more attention than the usual tourist to Thailand. If you are just a tourist, have packed like a tourist and intend on doing tourist things then you should have no worry at all.
Note this is just a guideline to set you off in the right direction; if you are unsure at all of immigration requirements you should double-check with your local Thai embassy.
Have a great trip!
