This is one of the best ESL resources I’ve stumbled upon in a while. Australia Network’s Learn English site has video courses for all types of English learners. There’s an IELTS course, a Business English course, a vodcast, and much more. They also have downloadable study guides and activity sheets.
This is a good four-part lesson on how to write an effective argument essay. This is tailored towards IELTS, but is useful for the TOEFL as well.
Here’s a three-part lesson on how to structure a letter. This would probably be more useful on the IELTS, but it could be helpful for TOEFL as well. The lesson starts off very basic, so if you already know the basics, feel free to start in the middle.
