Unfortunately multiple screen size support is a bit tricky on Android.
A very good start is the article at

Supporting Multiple Screens | Android Developers

which explains resolution and density concepts in Android.

For tablets, normally a 10' 1280x800 tablets as a 160/180 dpi density so it uses MDPI directory while a phone 4' 800x480 uses the HDPI.
You can create a large-mdpi and/or large-hdpi directory specifically for tablets (with a 7' or more screen) and put your graphics there.

You can create Large-Layout files for tablet and you can use different images for large layouts.
