If you are a winning player at the $10 level, I don't really see a need to "change your game" against your opponents. This type of thing comes with time, patience and practice. What you can do, however, is IMPROVE YOUR OWN GAME instead of trying to adjust to your opposition at this particular level.
$10 SNGs are basically all about ABC poker (SNG-style, of course). If you haven't alrady done so, I suggest you read
this, as it may be the single greatest post made in regards to beginning or low-limit SNGs ever.
