Assuming that you want to render your collection of nodes, you would use
node_view_multiple(). It's worth noting there's a node specific version of
With that in mind I imagine you're looking for code like the following:
$efq = new EntityFieldQuery();
$results = $efq->execute();
$nodes = node_load_multiple(array_keys($results['node']));
$views = node_view_multiple($nodes);
$output = drupal_render($views);
$output will contain a list of teasers representing the nodes found in the EFQ.
It's also worth noting this kind of logic should not happen in the template file, but rather in a preprocess function. This will prevent potential problems with caching later on, and is just good programming practice all-round.
