Mauricio Pochettino's men entertained and enthralled last term, providing Leicester's only real competition for the title.
However, the north Londoners, who have had to deal with a string of injuries, have found it tougher this campaign and sit 10 points behind leaders Chelsea.
Tottenham remain fifth after Sunday's 1-0 loss at Manchester United, whose tactics underlined to Kane that their style no longer comes as a surprise.
"People didn't expect us to play so well last year, and press so high with such intensity," the striker said
"Now teams are maybe dropping off a bit more, letting us have the ball - and we have to find different solutions to unlock the door.
"Manchester United made it difficult for us to play out from the back.
"They made us play more long balls than we are used to playing
That was their game plan, and it worked.
"All we can do is keep working on our game in training, working on different scenarios, and hopefully it will pay off
We have to keep fighting (in the title race)
We have no other option."
Kane was guilty of giving away the ball in the build-up to Henrikh Mkhitaryan's first-half winner at Old Trafford.
Pochettino defended his striker after the error and Spurs have the chance to make amends for the loss with back-to-back league matches at home to Hull and Burnley.
"Last year, December and January were the months when we pushed forward, got good results and moved up the table," Kane told the Evening Standard.
"We have to do the same again and we feel we can beat anyone in this league."
