@samundra
Thanks for the tutorial.
In my case i wanted to attach a form to the end of the contact page.
It really was this simple...

<?php
function aat_contact_entity_view( $entity, $type, $view_mode, $langcode ) {
 
  switch (
$type) {
    case
'node':
      if(
$entity->nid == variable_get('aat_contact_contact_nid',0)) {

       

$output = drupal_get_form('aat_contact_contact');
       
       
// create a new content field and stick the html in it
        // sink it to the bottom of the node
       
$entity->content['a_new_field'] = array(
             
'#markup' => drupal_render($output),
             
'#weight' => 99,
        );
      }
      break;
  }
}
?>

Taxonomy terms are rendered differently. You cannot use this hook to alter the taxonomy term page.
