Where to put hAtom author mark up?

Hi,
I had the following errors on Google Webmaster Tools:

Error: Missing required field “entry-title”.
Error: Missing required field “updated”.
Error: Missing required hCard “author”.

I managed to fix the first two errors (following these instructions https://fivera.net/hatom-feed-hatom-entry-error-wordpress-solution/), but I can’t figure out where to paste the code (<span class=”vcard author”><span class=”fn”></span></span>) for the author field.

Nothing in my code looks like what is suggested. Can you help me out please?

<?php if ( fp_get_settings( 'fp_show_post_author' ) == 1 ) { ?>
	<div class="entry-author">
		<div class="author-avatar">
			<?php echo get_avatar( get_the_author_meta( 'user_email' ), 68 ); ?>
		</div>
		<div class="author-description">
			<h4><?php printf( __( 'By %s', 'fairpixels' ), get_the_author() ); ?></h4>
		<?php the_author_meta( 'description' ); ?>
			<div id="author-link">
				<a href="<?php echo esc_url( get_author_posts_url( get_the_author_meta( 'ID' ) ) ); ?>" rel="author">
					<?php printf( __( 'Posts by %s <span class="meta-nav">→</span>', 'fairpixels' ), get_the_author() ); ?>
				</a>
			</div><!-- /author-link	-->
		</div><!-- /author-description -->
	</div><!-- /author-info -->
