NewMagickWand should be a static method in vala:

I don't think so. You should define a creation method instead:
[Compact]
[CCode (cname="MagickWand", free_function="DestroyMagickWand" )]
public class Wand {
    [CCode (cname="NewMagickWand")]
    public Wand ();
    [CCode (cname="MagickGetSize")]
    public bool get_size (out ulong width, out ulong height);
}
 

[Compact]
[CCode (cname="MagickWand", free_function="DestroyMagickWand" )]
public class Wand {

   [CCode (cname="NewMagickWand")]
   public static Wand new_magick_wand ();

   [CCode (cname="MagickGetSize")]
   public bool get_size(out ulong width, out ulong height);
}
