Florida Center for Reading Research is an excellent resource, especially for hands-on activities: http://www.fcrr.org/ Go to Resources, then Student Center Activities.
Check out http://www.readworks.org! Enter in grade level and skill and you get free passages and worksheets!
I frequently purchase units for my 4th and 5th graders from Bookrags. You can’t beat those!
Just Google the book you are interested in teaching. You are sure to find many ideas on how to teach reading strategies for it!
