Vientiane is the only thai consulate that doesn't require any of the proof ofz.
Penang requires proof of funds, onward travel and a hotel booking or lodging for at least a week.
K/L doesn't require proof of funds but it does require onward travel and proof of lodging for the entire trip.
HCMC/Hanoi Vietnam & Yangon are the same, proof of funds and onward travel.
