What is the best way to get a teaching job in Thailand as a new expat?

Hi, Everyone. I apologize if this question has been answered before here, but I am new here and would like some advice/help.

I am currently in the US and plan on coming to Thailand to teach asap. What is the best/quickest way to go about this? Should I get a tourist visa first, or should I come on a visa exemption and start looking for a job? Also what documents should I gather before leaving in order to eventually get a non-immigrant b visa. Should I get a background check? transcripts? etc? any help would be appreciated. thank you. I am very new to this and have seen a lot of different information. thank you again.
