a good book which you may find helpful is Learning Teaching by James Scrivener.
Basically, you divide a lesson into pre-reading, whilst-reading and post-reading activities.
A simplified version:
1) pre-reading - creating atmosphere, pre-teaching important vocabulary...
2) whilst-reading - asking questions before the actual reading, something to focus on (e.g. abc, true or false statements...)
3) post-reading - for example a discussion based on the text
Hope it helped a bit.
