I did this years ago when leaving the US. Pack like you are going for a week or less. 5 changes of most things. One pair of shorts. No toiletries. One pair of shoes. Everything I needed I found and for a lot cheaper in Asia. Also remember to take two credit or debit cards. Find a mail service that caters to expats. Don’t forget VPN. I would also be lost without google voice. It just saved me today when one of my cards got blocked and I had to call the bank. Google voice to the rescue. Finally smile a lot. Everyone will wonder what you been smoking or drinking.
