What type of beer are you looking for? Being that you are a homebrewer you have the option to brew whatever it is you personally want to drink. So let us know what you want to drink and we can point you in the right direction based on the ingredients you have. Now considering the fact that Singapore is roughly 75-90 degrees for the entire year, I personally would have a hard time drinking a large amount of Rauchbiers in that type of climate. It seems like more of a beer meant to be consumed in colder temperatures. That's just me though.
I actually live in Bangkok, Thailand, which never gets down into the 70s, unfortunately. I was referring to Singapore as the closest place I can get ingredients.
As far as the type of beer I would like, I would really like to brew a rauchbier (that's why I bought a rauchbier kit), but as I mentioned previously, I can't lager at the moment cause I don't have a dedicated fridge for it.
Since I am completely new to brewing, I don't know what my options are for utilizing the limited ingredients (or access thereto) to make an alternative beer style that can handle higher fermentation temperatures.
That being said, I have always preferred darker, and typically heavier beers. I love all styles really, but I have never been the type of person to drink a particular style based on the weather. This is especially true nowadays, otherwise I would only be drinking hot weather beers.
