Ahm, tough question.
Basically, you should check where you stand at the approach and across or at which target you play on the lane. About the target, there are different philosophies (looking at break point, the arrows, the dots at the foul line). And you should remember what at you did and what happened on the lanes. This is an important step for a consitent game and to make changes based on lane knowledge, not wild guesses.
Where to stand is the tough part. Every player is different, as well as the lane condition, the balls, the styles, etc. Some play deep, some close to the gutter, some with wide arcing shots, some with small controlled hook.
As a basic strategy to find "your" line, try to play straight up the 10th board for starters. Normally, you should have your feet 6-9 boards inside, and the shoulder and laydown point just above 10th board.
Watch the ball reaction, and adjust your feet accordingly (miss left, move left et v.v.) for 1-3 boards. repeat if necessary. If this simple adjustment is not enough, make an additional feet+target move in the miss direction, until you have a stable and comfortable path to the pocket. Remember it, it will be of great value for future starts.
Concerning spares, there are various adjutmenst systems for spares, and it also depends whether you convert them with the strike (hook shot) or a special spare ball (straight shot). Again, it is mostly a matter of feet adjustments and sometimes of the target into the desired direction for a hit.
For me, I will take out the single 7 pin playing my strike ball across my "normal" current pocket target (e. g. 3rd arrow), but move my feet 9 boards towards the gutter from the 1-3 pocket position, also taking out some speed just to let the ball roll and break softly. For the 10 pin, I use a polyester spare ball. I stand at 30th board with my right shoe tip, take out any side roll or lift from the release and play straight across 16th board at the arrows. But every player has a personal approach to this problem, you might check some bowling books about this topics.
