Node Full Content is displayed using node.tpl.php. If you would like to override tpl you can copy node.tpl.php and rename it to node--blog.tpl.php in your theme templates folder. For more information refer Drupal 7 Template Suggestions.

You can add Edit and Delete buttons using below code to the overrided template..

&lt;?php 
   if (drupal_valid_path('node/' . $node-&gt;nid . '/edit')) {
     print l('Edit', 'node/' . $node-&gt;nid . '/edit'); 
   }
?&gt;
&lt;?php 
   if (drupal_valid_path('node/' . $node-&gt;nid . '/delete')) {
     print l('Delete', 'node/' . $node-&gt;nid . '/delete');
   }
?&gt;
