Best bet would be to head to KL (Kuala Lumpur). If you don't like KL, then you could also have a good chance at finding work in Sabah or Sarawak.
The typical salary for English teachers ranges from 2500 to 3000 RM per month. International schools pay the best. Salaries can range up to 5000 RM per month if you're a good teacher.
Malaysians tend to prefer learning Queens English rather than American English. Quite a bit of demand for jobs in KL, and you wont break the bank by going a month or 2 without a job as the cost of living is quite cheap.
Recommended top schools would be:
British Council - Malaysia
ELS - Teach English in Malaysia
English Language School: International House Malaysia
