Create links for custom field query - wordpress

Question

All my post has a custom field created_by_alias, I am basically use the value in place of whereever author is used. I have customized the entry-meta function to display this value in plain text, I have also learned to build a query:
$query = new WP_Query( array('meta_key' => 'created_by_alias',
'meta_value' => 'somevalue' ));
Now for the final part: how to create a link for this piece of text, that brings a listing of all posts by this alias?
Do I need to write a template file or is there a quick way to reuse whatever code that generates links to a category, tag listing?

Not sure what you are looking for but seems to me that you want to show a link for the author posts in a specific page, if so, then you can use (using your query)
$query = new WP_Query( array('meta_key'=>'created_by_alias', 'meta_value'=>'somevalue' ));
If $query returns result and you have the id then you can use
echo get_author_posts_url( $query->posts[0]->ID ); // the `ID` from first row
Or for multiple rows, you can loop like
if ( $query->have_posts() ) {
while ( $query->have_posts() ) {
echo get_author_posts_url( get_the_ID() ) . '<br />';
}
}
Once this link is clicked, then posts will be retrieved and will be shown according to your page hierarchy, if no author template was found then finally the inedx.php will be used.
Also, if you need a custom template and want to query
$posts = get_posts(array($ID);
Now, to get the id you an use
get_user_by( $field, $value ); // 'id', 'slug', 'email', or 'login'
So, if you have the login name of the user, for example admin then you can use
$id = get_user_by( 'login', 'admin' )->ID; // php 5+
// or
$user = get_user_by( 'login', 'admin' );
$id = $user->ID;
Then get the link and echo it, whereever you want
echo get_author_posts_url( $id );
