I am going to assume you want to align it left, so here is a copy and paste with the text alligned.
Code:
<!-- Start Post Thank You Hack -->
<div align=left>
<if condition="$post[userid]">
[ <strong>$vbphrase[post_thanks_thanks]:</strong> $post[post_thanks_user_amount_formatted] ]
<if condition="$post[post_thanks_thanked_times] == 1">
<strong>$vbphrase[post_thanks_time_post]</strong>
<else />
<if condition="$post[post_thanks_thanked_posts] == 1">
<phrase 1="$post[post_thanks_thanked_times_formatted]">$vbphrase[post_thanks_times_post]</phrase>
<else />
<phrase 1="$post[post_thanks_thanked_times_formatted]" 2="$post[post_thanks_thanked_posts_formatted]">$vbphrase[post_thanks_times_posts]</phrase>
</div>
</if>
</if>
</if>
<!-- End Post Thank You Hack -->
EDIT- sorry, late post, but you might just want to use a lot of Its just a single space in HTML.
