Login/Register Icon

Hi

I'm using the following hook for login/register, as it switches to account once logged in.

<?php if ( is_user_logged_in() ) { ?>
 	<a href="<?php echo get_permalink( get_option('woocommerce_myaccount_page_id') ); ?>" title="<?php _e('My Account','woothemes'); ?>"><?php _e('My Account','woothemes'); ?></a>
 <?php } 
 else { ?>
 	<a href="<?php echo get_permalink( get_option('woocommerce_myaccount_page_id') ); ?>" title="<?php _e('Login / Register','woothemes'); ?>"><?php _e('Login | Register','woothemes'); ?></a>
 <?php } ?>

I would like to add the fa-user icon to the left, how to add this?

Thanks
