There are many teaching abroad programs that pay students, but if you are restricted to programs during school holidays, you may not be able to find a paid job. Especially if you have specific countries in mind, you are more likely to find placement as an unpaid teacher.
Find an internationally sponsored teaching program for which you qualify. Your qualification for certain teaching programs will most likely depend on your area of study. For instance, if you are working on an undergraduate degree in German, you will probably not qualify for a teaching abroad program in Germany because there is little need for German language instruction. However, you may qualify to teach English as a foreign language in Germany. To search through a list of programs, visit TeachAbroad.
