To get low-fare flights, basically what you need to do is HUNT. Get into hunting mode and start:
1) Use a fare-compare search engine like http://www.skyscanner.net/ to check for lowest fares and airlines available. Google for other fare compare websites (generally those that quote in USD or GBP are more expensive)
2) Know the airlines that fly the destination you are looking at and whenever possible, remember their airport codes
e.g. Kuala Lumpur KUL; Singapore SIN
There are five airports in London - Heathrow LHR, Gatwick LGW, Stansted STN, London City Airport LCY and Luton LTN (Google map below should give you an idea). Not all airlines operate at all these airports so it is important to check whether the ones you are looking at do. Be sure also to check distance and where you need to go from there for convenience.
If you are not picky, the one that's said to be furthest - Stansted - is only an hour bus ride from town and generally plenty of busses and train are available to take you where you need to go.
Here's a list of other airlines connecting KUL London.

3) Check individual airline websites for promotional fares - now is the best time to start monitoring - sign up for promotion notifications so you will be notified when they have one
4) Lookout also for travel fairs and always compare prices
5) If you will need hotel stay, explore also sites that offer hotel + flight packages such as Air Asia's goholiday.com
6) Once you are familiar with what the normal fare is, you can be decisive when a promotional fare appears.
Hope this helps, more tips in next post! Happy hunting :)
