Use zend view placeholder helper

In your layout.phtml

<?php if(!$this->placeholder('hide_login_form')) :?>
<?php echo new My_Login_Form(); ?>
<?endif:?>

Now Inside your login Action where you want to render full page form do

public function loginAction()
{
 $this->view->placeholder('hide_login_form')->set(true);
}
