Without knowing what resourses you will have it's difficult to know where to begin. However, here goes. I teach a similar age group here in Italy and I've found that one mistake many teachers make is to speak too much. Try to speak as little as possible but when you do, speak clearly and slowly and don't worry about getting silence in reply. It takes time for beginners to process language and them speak it.
At this age many short activities rather than one long one are more effective. I use a lot of games, songs and especially pictures with my classes. You might want to take pictures of your family with you as I've found children are very interested in the teacher.
Most importantly be clear about the aims of the lesson. Are you teaching introductions, prepositions
of place, the past simple etc? This does not mean that such jargon needs to be known by the students, at least at the beginning, but it is important that you know exactly what you are trying to teach. For this reason, especially if you are new to teaching, I find a course book essential as it gives a structure to the students learning (and saves you a lot of work). Unfortunately I've seen a lot of bad course books in Asia with anything up to fifty new words, which the students are expected to memorise, in each chapter. Whatever book you end up using try to "bring the course book to life" Easy to say, not so easy to do. I often look at the aims of each chapter and then try to think of interesting ways the material in the book can be exploited. For example, if you have a dialogue about buying things in a shop bring in lots of real objects and after they've practiced the dialogue get them to set up "shops" in the classroom and buy and sell to each other. Similarly with numbers set up "train platforms" in the classroom read out train anouncements and the students have to listen and go to the correct platform. I'm sure you can think of many more such ideas yourself.
Two final thoughts, drilling students seems to be quite a controversial technique in EFL teaching. My own view is that it is a very important technique to use, especially with Asian students who very often need the support of their classmates when practicing difficult English sounds such as "TH." Above all enjoy yourself. A happy teacher is also a good teacher.
Best of luck with the teaching
