Getting $content of content type in template.php
I'm not sure, if this is what you are looking. But if you want to embed a node-add form you could use the following code.

&lt;?php
$node = new stdClass();
$node-&gt;type = 'machine_name_of_your_content_type';
module_load_include('inc', 'node', 'node.pages');
$output = drupal_get_form('machine_name_of_your_content_type_node_form', $node);
print $output;
